Application filed May 17, 1912.

La,- all who; it may comm Be it known that I, RONALD F. MCFEELY, t citizen of the Ynited States, residing at Beverly, in the county of Essex and State of li lassachusetts, have invented certain 1mproveinents in Lasting-ldachines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and more particularly to lasting machines of the type described in United States Letters Patent No. 584,7 l4, dated June 15, 1897. Lasting machines of the type described in said prior Letters Patent and commonly known as hand method lasting machines have usually employed a reciprocating, presser or wiper for stretching and laying down the edge or margin of the upper, especially around the toe, to force the upper into the angle of union between the feather edge and lip or rib of the innersole. By this means, the upper is worked into proper position to be secured by temporary tacks or y a wire binder and, at the same time, the overlaying or plaiting action of the pincers is materially assisted. To correct various defects experienced and to obviate certain disadvantages found in the use of the reciprocating presser of said Letters Patent, there have been proposed various disk wipers arranged either to have a continuous rolling engagement with the upper or to be rotated in engagement with the stock by po er driven means.

The present invent on is directed to DIO- viding for use in machines of the said type a rotary wiper which, while retaining all the advantages of anv rotatable wiper heretofore proposed. will, at the same time, be more efiicient in operation and of more universal adaptability.

In the use of machines of the type of said Letters Patent it has been found diflicult to last satisfactorily parts of the shoe where the outstanding upper materials are especially stiff and bulky. This difficulty is most pronounced around the toe portion of the shoe where the upper is usually plaited with the result that very powerful wiping action is required to supplement the everlast- Specification of Letters Patent.

edge formation of the wiper preferably being such that, as it is rotated in engagement with the upper, it delivers against the upper repeated distinct blows of progressively increasing force which have a most powerful wiping action on the upper. Also, in accordance with another feature of the invention, the illustrated wiper is formed to be out of stretch obstructing engagement with the upper during the updra win movement of the pincers, during which movement operative engagement of the wiper with the upper is decidedly disadvantageous. v

In addition to these and other features and characteristics of general applicability, the embodiment of this in ention shown in the drawings and hereinafter described in detail presents features which render it especially suited for use on McKay work,

upon which class of work rotary wipers as heretofore constructed and arranged have not been used, as I am advised. In o der that on lllcKav work. with respect to wh ch it is the p actice to lav the pla ts in d fferent d rect ons along the two sides of the center o the toe. the wi er ma not o ose and tend to ndo the nla ts on either side of the toe. the i st ated wiper is a anged for rotat n in d rect ons correspond ng to the two direct ons of nla t ng mo ement of the pince s so that the wiper ma alwa s be rotated in the d rect on in which the plaits are laid and the edge format on of the wiper is such that in whichever direction the plaits are laid the wiper will exert during the plait ng motion a progressively increasing wiping action in the direction of the plaiting,

furthe ad antage resulting f om the mess formation and mode of operaillu tion of the wiper is that distinct blows of progressively increasing force delivered by the wiper against the upper are directed always in the direction of feeding movement of the shoe and tend to carry the shoe along to an extent which greatly aids the operator in feeding the work. At the same time whenever a toe binder wire is to be applied, these characteristics enable the wiper by repeated blows against the wire to set the wire deeper into the angle between the feather edge and lip or rib of the innersole than has hitherto been possible.

These and other features and advantages of the present invention will be apparent from the following detailed description read in connection with the drawings which illustrate in what manner the invention may be embodied.

Referring to the drawings: Figure 1 is a side view in elevation of a portion of a lasting machine of the type referred to, showing the present invention applied thereto; Fig. 2 is a top plan view of the wiper and associated supporting and operating parts according to one construction of the operating mechanism of the wiper; Fig. 3 is a side view in elevation of the wiper and operating mechanism therefor of Fig. 2; Fig. 4 is a detail in plan view of the pawl and ratchet construction of Fig. 2 for effecting intermittent rotation of the wiper; Figs. 5, 6, 7, 8, 9 and 10, illustrate different stages in the operation of the wiper of the present invention, Figs. 7 and 9 bein vertical sections of Figs. 6 and 8, respectively; Fig. 11 shows the toe portion of a McKay shoe being lasted with the aid of the rotary eccentric wiper; Fig. 12 is a similar view of the toe portion of a welt shoe showing the operation of the rotary wiper in the lasting thereof; Fig. 13 is a top plan view similar to Fig. 2, illustrating a second and alternative form of operating mechanism for the wiper which is covered by the generic claims herein and will be specifically claimed in another application; Fig. 14v is a side view in elevation of the operating mechanism shown in Fig. 13; Fig. 15 is a view on an enlarged scale and taken at an angle, showing the wiper and a portion of the supporting and operating mechanism of Fig. 13; and Fig. 16 is a perspective detail in elevation of the clutch mechanism of Fig. 13.

The machine to which by way of illustration this invention is described as being applied comprises a column A (Fig. 1) which supports a framework or head B on which are mounted the various operating parts of the machine including the upper lasting pincers and controlling and operating mechanisms therefor. The shoe is operated upon in machinesof this type by holding the last bottom upward against the bottom rest 1 and a side or edge rest 2. Pincers 3 mounted at the front of the machine are operated by suitable mechanisms from a main cam shaft 5 journaled in the head B of the machine. The pincer operating mechanisms cause the pincers 3 first to descend and grip the edge of the up er. After the pincers 3 have secured a E1111 hold on the margin of the upper of the shoe, they are moved first upwardly and then inwardly toward the center line of the sole to draw the up er uniformly and evenly to the body of the ast in position to receive a fastening tack or to have a binding wire applied to the upper. The upper is then held in this position by the pincers while the tacker mechanism drives the tack through the upper and thus secures it temporarily in position at the point of insertion of the tack. Tacks are supplied to the tacker mechanism in position to be inserted by a driver 6 (Fig. 1), from a double raceway 8 adjustable to feed different size tacks to a tack carrier or tack block 10 which, in addition to holding the tack for the tack driving operation, serves as a presser to hold the stretched and overlaid upper in tack receiving position for the insertion of the tack after the pincers have retreated preparatory to stretching and overlaying another portion of the margin of the shoe upper.

In addition to the upward stretching or updraw movement of the pincers 3 and the overlying or overdraw movement of the said pincers, it is desirable at times, particularly in lasting around the toe and sometimes at other points, that the pincers have imparted to them other movements to fold or plait the upper in order satisfactorily to dispose of the fullness of upper materials at these points. In order thus to move the pincers to plait the upper at the toe or whereever it is desired to plait the upper, suitable mechanism operated from a cam on the main shaft5isprovided. this mechanism including adjustable means for rendering the mechanism for imparting the plaiting movements to the pincers operative or inoperative as desired through movement of a knee lever 12 (Fig. 1) which turns a vertical rock shaft 14, movement of the rock shaft 14 in turn through suitable connections operating a sliding block (not shown) wh ch is arranged to start, stop and change the direction of the plaiting motion of the pincers for right or left plaits in a manner well known in this type of machine.

For a full disclosure of the complete machine to which the present invention is described as being applied and for a complete description of the construction and operation of the above mentioned mechanisms and parts, reference should be had to said prior Letters Patent No. 584,744. Reference should also be had to'saidpatent for other details of construction and operation of parts not fully described herein since, except ashereinafter indicated and described in detail, the construction and operation :mavmost conveniently be asdescribed and explained in said prior patent :It is also desirableor necessary in lasting around the toe and sometimes at other :points to employ a wiper or presser which shall supplementthe wiping action of the reciprocating tack block 10 in order tobend down the stiff and bulky outstanding upper r 'materials and, in making welt shoes, to

crowd the margin of the upper down into the angle of union :between the feather edge and lip or rib of the innersole. The wiper of the present invention, indicatedat 16, is

pivoted eccentrically, instead of concen- 'trically asheretofore proposed, and is supported on a bridge 18 (Figs. 2, 13 and 15) connecting two wiper carriers and 22. The wiper 16 maybe either intermittently or continuously driven, Figs. 3 and 1 illustrating operating mechanism for intermittently rotating the wiper and Figs. 13 to 16 showing as a second and'alternative construction, operating mechanism arranged to rotate the wiper 16 uninterruptedly and con tinuouslv. According to the first construction (Figs. 2, 3 and 4-), the wiper 16 is connected by speed increasing gearing to a pawl and ratchet device operated through suitable connections with the main cam shaft According to the second construe tion the wiper 16 is geared to a horizontal shaft having a clutch connection with a vertical shaft continuously rotated from the said cam shaft 5.

In the first construction, a toothed pinion 24 (Fig. 2) secured to the under side of the wiper 16 meshes with a gear 26 which is operated by a gear 28 secured to a ratchet wheel 30. T he ratchet wheel 30 is pivoted by a stub shaft 31 (Fig. 3) to the under side ofa bracket plate 32 projecting from the bridge 18. Located on either side of the ratchet wheel 30 are operating pawls 33 backed by spring plugs 34 and mounted on a pawl carrier 35 carried by a plunger 36 (see particularly Fig. 1). The plunger 3t is forked at its front end to straddle the stub shaft 31 and is operated by a. lever 38 fulcrumed on the frame at 4L0 and having ball and socket universal joint connection 12 with a lever as fulcrumed on the frame at and operated from a special cam on one face of the cam block e6 on the main cam shaft 5 (Figs. 2 and 3). The construction is such that each forward stroke of the plunger 36 operating, through the speed increasing gearing 2 1-, 26, 28, to cause the ratchet wheel 30 to be advanced the length of one tooth causesa complete rotation of the wiper "16- to be effected. This construction and arrangement provide for causing a complete rotation of the wiper 16 tooe effected during :each cycle of operations of the r machine.

:The wiper of the present invention is especially designed and arranged'to be out'oI stretch obstructing engagement with the upper duringthe updrawing movement of the pincers, during which movement operative engagement of the wiper with the upper is disadvantageous, and to exert a progressively increasing and powerful wiping action upon the upper during the overdrawingof the upper into ov rlasted position when, es- 'pecially at the toe by reason of'tlie bulky :nature of the upper materials, aparticularly eticient wiping action is required to crowd .the upper snugly into the angle between the feather edge and lip or rib of the innersole. wiper 16 comprises an inoperative portion 48 which is relatively narrow considered from thecenter of rotation 50 of the wiper l6'to its peripheral edge and is formed to be out of stretch obstructing engagement with the upper, and a wider operative portion 52 progressively increasing in width from the center of rotation of the wiperto its peripheral edge (Figs. 5 to 12). Preferably, too, the progressively widening portion of the wiper 16 is follow-ed'by a portion 54 of maximum width from the center of rotation to the periphery of the wiper which portion 5% exerts a cumulative wiping action on the upper and also serves to assist in holding the upper in overlasted position for the insertion of the tack or the application of the toe binding wire. In view of the fact,

that for operating on McKay work, with respect to which it is the practice to start at width from the narrow inoperative portion 1 418 of the wiper 1 3 to the portion of 'maxi mum width 5-1 so that one of said operative portions 52 always progressively increases in width in the direction of rotation of the wi er 16 and e other similarly decreases in width for the purpose of enablin the wiper 16, in which-e er direction it is rotated, to exert a progressively increasing wiping action on the upper during part of the cycle of operations of the machine. As shown, the narrower and inoperative portion 48 of the wiper 16 and the portion of maximum width are concentric with the center of rotation 50 of the wiper while the twin graduated portions 52 connecting the Accordingly, the illustrated eccentric portions 48 and 54 are eccentric with relation to the said center of rotation of the wiper. This particular arrangement although convenient is, however, obviously not essential since the inoperative portion 48 may be either eccentric or concentric, provided it is arranged to be out of operative engagement with the work at all time. Similarly, the twin graduated portions 52 may be laid out, for example, on a spiral, the only essential features of their construction being that they shall respectively progressively increase or decrease in width in the direction of rotation of the wiper.

The twin graduated operative parts 52 and the connecting operating portion of maximum width 51 are preferably provided with peripheral fingers 56 which, by reason of the graduated formation of the said operative portions 52 of the wiper, vary progressively in height from one terminus to the other of each of the respective operative portions 52, since it has been found in practice that this edge formation of the wiper exerts a more effective wiping action on the upper than does a wiper having a smooth uninterrupted peripheral edge. In view of the fact that the inoperative part 48 of the wiper is so formed relatively to the operative parts of the wiper as to be out of stretch obstructing engagement with the upper at all times, the formation of its peripheral edge is, of course, of no great consequence. Conveniently, and as shown, however, the narrow and inoperative portion 48 of the wiper may have a. smooth uninterrupted peripheral edge.

The above described formation of the wiper provides that during the overlaying or plaiting movements of the pincers the wiper 16 will deliver against the upper distinct blows of progressively increasing force with the result that not only is the upper crowded most eiiiciently into the angle between the feather edge and lip or rib of the innersole but also, when it is desired to apply a toe binder wire, that wire indicated at 58 (Fig. 12) will be crowded into and set most snugly in the said angle, to this end the work engaging edge of the wiper 16 being further provided with a slightly undercut or beveled formation and the toe binder wire guiding means being arranged to guide the wire 58 along the peripheral edge of the wiper so that the wiper overlies the wire and acts directly thereagainst.

The wiper 16 is preferably so set and timed relatively to the pincer movements that, when the pincers 3 seize the upper stock just prior to'the updraw, the middle point of the narrow inoperative portion 48 of the wiper 16 (indicated at 60 Fig. 5) substantially registers with the vertical line of updrawing movement of the pincers (Fig. 5) so that, starting from its initial position as shown in Fig. 5, rotation of the wiper 16 in either direction will cause the wiper to be out of stretch obstructing engagement with the upper during the updraw and until about the height of the updraw is reached (Figs. 6 and 7), during which time one half of the narrow inoperative portion of the wiper is passing over the work, and to exert a progressively increasing wiping action on the upper durin the overlaying or plaiting movement 0 the pincers. At the conclusion of the plaiting motion of the pincers 3 (Figs. 8 and 9), the pincers let go of the stock and a tack 62 is driven on McKay work (Figs. 8, 10 and 12) or the binder wire 58 is applied on welt work (Fig. 12) the portion of maximum width 54 of the wiper 16 after the pincers 3 let go of the stock having a cumulative action on the upper and at the same time assisting the tack block 10 in holding the upper for the driving of the tack 62 or the application of the toe binder wire 58 (Fig. 10). While the portion of maximum width 54 of the wiper is in engagement with the stock, the pincers 3 are being restored to normal position and after the portion 54 of the wiper has passed out of engagement with the stock and during the movement over the stock of the succeeding graduated portion 52 of the wiper 16, the pincers 3 are lowered and opened preparatory to gripping a fresh portion of upper. Because of the difficulty in satisfactorily crowding the bulky plaits (indicated at 64 Figs. 11 and 12) into lasted position, the above mentioned provision for exerting a progressively increasing wiping action on the upper during the entire interval between the beginning and conclusion of each plaiting movement of the pincers 3 in whichever direction the plaits 64 are laid constitutes an important feature of the above described arrangement. Further, by reason of the above described reversible character of the wiper formation, after the portion of maximum width 54 has passed out of engagement with the upper, the wiper 16 of course begins to back off from the upper during the progressive narrowing of the succeeding graduated part 52 of the wiper. In view of this fact, the operating means for the wiper 16 may be arranged so that the latter part of the rotation of the wiper during which the wiper backs off from the upper is effected more quickly than that part of the rotation of the wiper during which its principal wiping action is exerted, the result being of course that the wiper 16 finishes its complete rotation long enough before the conclusion of the cycle of operations of the pincers so that the pawl operating mechanism is returned and ready to initiate the next rotation of the wiper at the desired time. To this end. the cam on the main shaft 5 which operates the plunger 36 through the levers 38 and 44 is preferably formed to cause the latter part of the operative stroke of the plunger 36 to take place more quickly than the first part thereof, the plunger 36 thus having an irregular though uninterruptedmotion. Advantageously,too, when the machine is to be used on McKay work where it is desired to tack the upper around the toe, the timing of the plunger operating cam may be such that the portion of maximum width 54 of the wiper 16 will have passed out of engagement with the work and the wiper 16, will have begun to back off from the work before the tack 62 is driven, this in order to form and then uncover a smooth seat for the reception of the v said tack.

Preferably, the supporting means for .the wiper 16 are arranged so that the wiper 16 may be withdrawn out of the operative p.0 siticn shown in Figs. 2 and 13 when it is not desired to. use the wiper. In order that the wiper 16 may be adjusted into and out of said operative position, the wiper carriers 20 and 22 which constitute the bifurcated ends of a slide 618 are arranged to be moved out and in, toward and from the work by sliding engagement of an anti-friction roll carried at the rear end of the slide 68 with the front edge of a cam faced slide 72 (Figs. 2 and 13). rlnti-friction rolls 74 are also provided for facilitating movement of the wiper carrier slide 68. Springs 76 and 78 arranged on either side of the slide 68 and substantially in line with the bifurcated wiper carrier ends 20v and of the said slide are passed through slots 80 in the machine frame under the slide 68 and abut at their front ends against shoulders formed in the frame by the ends of the slots 80 and at their rear ends are secured to pins 82 carried by the slide 68. The springs 76 and .8 are suitably tensioned and operate normally to draw the wiper carrier bars 20, 22, backwardly to. keep the friction roll 70 at the rear of the slide 68 in engagement with the cam face of the slide 72. Endwise movement of the slide 72 operates to move the wiper carriers 20 and 22 out and in according to whether the roll 70 on the wiper carrier slide 72 is in engagement with one of two high parts 84 on the slide 7 2 or in engagement with a recess 86 in the face of the endwise movable slide 72, movement of the slide 72 to bring the roll 70 against either of the high parts 84 on the slide '4' 2 pushing the wiper carrier slide 68 and wiper carriers 20 and 22 outwardly to bring the wiper 16 into operative position as shown, for em ample, in Figs. 2 and 13. Conveniently and as shown, movement of the wiper carrier slide 68 out or in to bring the wiper 16 into or out of operative position may be arranged to be controlled by m vement of the knee lever 12 to inaugurate or stop the plaiting motion of the pincers. To this end, as shown on the rock shaft 14 is mounted one end of an arm 88, the free end of which is slotted at 90 to embrace a pin 92 on one end of the endwise movable cam slide 72, movement of the arm 88 induced by turning movement of the rock shaft 14 operating through the pin and slot connection 90, 92, to effect endwise movement of the cam slide 72 to move the wiper carrier slide 68 out or in. Anti-friction rolls 94 carried in the frame of the machine operate by engagement with the rear side of the endwise movable. slide 72 to facilitate operative movement thereof. The arm 88 which operates the, endwise movable slide 72 is so set on the rock shaft 14 that when the rock shaft 14 is in its neutral or inoperative position, in which position no plaiting motion is imparted to the pincers, the slide 68 and wiper 16 will be in their retreated and inoperative postion, while movement of the knee lever 12 one way or the other to institute or vary plaiting motion of the pincers in one direction or the other will cause the roll 70 to ride upon one or the other of the high parts 84 of the slide 72 to bring the wiper 16 into operative. position.

In the second construction shown in Figs. 13 to 16, inclusive, the wiper supporting and controlling means are as in the first construction, the second construction differing from the first in the wiper operating mechanism, this mechanism in the second construction being adapted to turn the wiper continuously and uninterruptedly in either direction. In the construction of Figs. 13 to 16, the, wiper 16 is connected by gearing to a horizontal shaft 96 having a clutch connection with the main cam shaft 5. The gearing connecting the wiper 16 to the horizontal shaft 96 comprises a pinion 98 secured to the under side of the wiper 16 to rotate the said wiper and meshing with a toothed gear 100 pivotally secured as by a screw threaded bolt 102 (Fig. 15) to a cutaway portion of the bridge 18, the gear 100 having secured to its under side by the bolt 102 a downwardly projecting bevel gear 104 meshing with a bevel gear. 106 set at right angles to the bevel gear 104 and carried on a boss 108 pinned to the horizontal shaft 96 for rotation therewith by a pin 110. The horizontal shaft, 96 is supported at its forward end in a bearing 112 into which the end of the, bolt 102 is threaded, acap 114 and bolt, 116 (Fig. 15). restraining the shaft 96 from endwisemovement in the direction of its operating mechanism. On the rear end of the rotatable shaft 96 is splined a clutch member 118 (Fig. 16). between oppositely faced bevel gears 120 and 122 between bushings 124 and 126 and spaced apart; a distance, greater. than the width of the clutch member 118, each of the gears 120 and 122 meshing with a bevel gear 128 carried on the lower end of a vertical shaft 130, the upper end of which is operatively connected with the main driving shaft 5 by a horizontal spiral gear 132 meshing with a vertical spiral gear 134 on the main shaft 5. The bushings 124, 126 are carried in a housing 136 which may be integral with or secured to the frame of the machine while the vertical shaft 130 projects through a portion 138 of the machine frame and is journaled in a bushing 140 in a plate 142 set between the portion 138 of the machine frame and the housing 136. The clutch member 118 is brought into clutching engagement with one or the other of the gears 120, 122 by a yoke 144 carried by an angle lever 146, the rear arm of which is forked to be engaged at one or the other end by a projection 1.48 (Fig. 13) from the cam faced slide 72, adjusting movements of which, as in the construction first described, are effected by movement of knee lever 12 through the'lever arm 88 and pin and slot connection 90, 92. The angle lever 146 is so set that when the knee lever 12 and post 14 are in their central or neutral position, in which position no plaiting motion is imparted to the pincers 3, neither of the bevel gears 120, 122, will be operatively connected with the central clutch member 118 so that as a result when the knee lever 12 is in its neutral position and no plaiting motion is imparted to the pincers 3, the rotary wiper 16 will be at rest. Movement of the knee lever 12 one side or the other of its central or neutral position to initiate the plaiting motion of the pincers 3 at the same time through the projection 148 from the cam faced slide 72 operates the angle lever 146 to bring the clutch member 118 into operative engagement with one or the other of the gears 120 and 122 and thus to rotate the wiper 16. In order that the clutch shifts may be made yieldingly to prevent possible breakage of parts, the ends of the angle lever 146 carry spring plugs 150 (Fig. 13) and a spring pressed centering wedge 152 operates so to position the angle lever 146 as to insure that neither of the gears 120, 122 is in driving engagement with the gear 128 when the knee lever 12 is in its central and neutral position and rotation of the wiper 16 is not des red.

The arrangement of the above described wiper operating mechanism is such that as in the first construction the wiper 16 has a complete rotation imparted to it during each cycle of operations of the machine, the form and the timing of the parts in this construction being such that during the rotation of the wiper, the same relation is maintained between the parts 48, 52, 54 of the wiper edge and the pincer movements except that a complete rotation of the wiper OCGUPIBS exactly the time of one cycle of operations of the pincers 3, in order to maintain this relation during successive rotations of the uninterruptedly operated wiper. It is desirable also that the wiper 16 be always rotated in the direction in which the plaits 64- are laid, since otherwise the wiper would oppose and tend to undo the plaits. Most conveniently and according to both illustrated constructions the wiper 16 is arranged to have its direction of rotation automatically controlled by movement of the knee lever 12 and rock shaft 14 to control the direction of plaiting motion of the pincers 3. To this end, in the first construction the pawls 33 are arranged to be moved into operative relation with the ratchet wheel 30 by engagement of pins 153 (Fig. 4) with a shifter 154 pivoted at 155 to a bracket 156 on the machine frame. The shifter 154 is operated by a link 157 pivoted at one end to the said shifter 154 and having a pivotal connection from its other end to the rock shaft 14 so that movement of the rock shaft 14 one way or the other induced by movement of the knee lever 12 to cause plaiting motion to be imparted to the pincers 3 in one direction or the other operates .through the link connection 157 with the shifter 154 to cause one or other of the pawls 33 to be brought into operative connection with the ratchet wheel 30 to cause rotation of the wiper 16 to be effected automatically in the direction of the plaiting. In the second or alternative construction, the same result is obtained by causing operative movement of the central clutch member 118 to be effected by the knee lever 12 through the rock shaft 14, lever arm 88, and projection 148 from the cam faced shaft 72 operating one part or other of the forked end of the angle lever 146. A further advantage from causing the direction of rotation of the wiper always to correspond to the direction of plaiting arises from the fact that the wiper is thus always caused to be rotated in the direction of feeding movement of the shoe. As a result, because of the eccentric formation of the wiper 16 and consequent progressively increasing action exerted by the wiper always in the direction of feeding movement of the shoe, and by reason of the distinct blows given with progressively increasing force by the peripheral fingers 56 of the wiper 16, the wiper 16 tends to carry the shoe along, exerting a considerable feeding action on the shoe and thereby greatly assisting the operator in advancing the work. Furthermore, as shown in the first construction, the connection of the link 157 with the pawl shifter 154 and rock shaft 14 is such that when the lrnee lever 12 and rock shaft 14 are in central or neutral position, in which position, as is fully explained in said Letters Patent, no plaiting motion is imparted to the pincers 3, neither of the paw-ls 33 is in operative engagement with the ratchet Wheel 30 and, consequently, the Wiper 16 has no rotative movement imparted to it While similarly, in the alternative construction the lever arm 88 is so set on the rock shaft 14: that When the knee lever 12 and rock shaft 14 are in their central or neutral position, the clutch member 118 Will be in a central and inoperative position and the horizontal shaft 96.through which motion is imparted to' the Wiper 16 Will be at rest. As a result, the starting and stopping of the Wiper 16 as Well as movement of the Wiper into or out of operative position, and the direction of its rotation are, in both illustrated constructions, automatically controlled by move ment of the knee lever 12 to control the plaiting motion of the pincers. It is of course not essential, however, that the Wiper 16 be controlled automatically upon movement of the knee lever 19 to control plaiting motion of the pincers, since obviously the Wiper 16 may be controlled entirely independently of the means for controlling plaiting motion of the pincers it so desired.

it is important that provision be made for insuring that, Whenever in the cycle of operations of the machine the knee lever 12 is moved from its neutral position to con nect the means for imparting plaiting motion to the pincers 3 With their source of power and to throw the Wiper 16 into operative position and at the same time either render one of the paWls 33 operative With respect to the ratchet Wheel 30 in the first construction or move the clutch member 118 of the second construction into operative position, that the Wiper 16 shall always become operatively connected With the shaft 5 to begin its rotation at the same point in the cycle of operations of the machine. In the first construction, the timing of the cam Which operates the plunger 36 is such that rotation of the ratchet Wheel 30 can only be initiated at a single point in the cycle of operations. In the second construction, the same result is produced by providing each side of the clutch member 18 with a single tooth 1.59 (Fig. 16) arranged to drop into a single notch 160 in the inner side of the hub of the adjacent bevel gear 120 or 122.
